// This test is asserting that a single property/element access
// on `this` is a special assignment declaration, but chaining
// off that does not create additional declarations. I’m not sure
// if it needs to be that way in JavaScript; the test simply
// ensures no accidental changes were introduced while allowing
// element access assignments to create declarations.
